Down the Halls of HVAC

hallsLooking at heating in St Louis near Sunset Hills, we realize that is has been some time since we perused the halls of an HVAC explanation, looking for new details to point out surrounding your system in St Louis.  So, today, we stumble upon the heat exchanger. “The heat exchanger is found inside your furnace unit’s housing. This component switches on when the furnace is activated by thermostat to produce warmer temperatures in winter.” The way it operates is to pull in cool air, then heat it and circulate it by way of your ducts and our through your vents.

The heat exchanger pulls in cool air, heats it, and circulates the resulting heated air via your ducts and out through the vents.  The evaporator coil is another important heating component to understand.  It has, basically, the opposite job of the heat exchanger and it acts to cool the air when the thermostat is set lower and cooler during the summer months.  “Located in a metal enclosure on the furnace’s exterior, to the top or side, the evaporator coil works similarly to an automobile radiator to produce cool air, which is then circulated through the ductwork.”

Now, we move onto the condensing unit of your heating and cooling system in St Louis near Sunset Hills.  Connected to the evaporator coil, the condensing unit is installed by HVAC contractors on the outside of your home and filled with refrigerant gas in order to properly operate. “When the refrigerant has been cooled to a liquid by heat exchange with the exterior air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more.”  This leads us to your refrigerant lines which carry the refrigerant substance to the condensing unit vaporized in the form of gas and return it to the evaporator coil in liquid form.  In order to be resistant to temperature, these lines are typically made of copper or aluminum.

Different Components of Your Cooling System

heat exchangerFrom the world of heating and cooling in St Louis near Wentzville, there exist many different components, all of which are designed to serve a purpose and many of which fly under the radar of our complete understanding.  We set out to change that, one element at a time and we are now looking at the refrigerant lines in your St Louis cooling near Wentzville MO. “The refrigerant lines carry a refrigerant substance to the condensing unit vaporized in the form of a gas, and return it to the evaporator coil in liquid form. These ‘lines’ are actually narrow tubes manufactured from a durable heat- and cold-resistant metal such as copper or aluminum.”

Now we arrive at the ductwork. In an HVAC system in St Louis, the ductwork refers to the system of ducts that transports air warmed or cooled by the system to the various areas of your home. These ducts are commonly made of lightweight aluminum. However, they may also be manufactured from steel, flexible plastic, polyurethane, fiberglass, or fabric.  Then we see the vents in your heating and cooling system in St Louis MO.  These are typically rectangular outlets where heat or cool air is transferred from the duct system to the actual rooms and spaces to be heated and cooled.

Elaborating more completely on the vents, we see that the metal is “Made of high- and low-temperature safe metal, similar to the lines we discussed earlier within the HVAC system.  The vents are located on or near the ceiling and are usually fronted with angled slats (“vents”). “These vents direct the treated air downward to where people are using the room. Often they may be manually controlled or even closed, to control the amount of heating or cooling and the area of the room to which it will be directed.”

Some Will Clean HVAC for the Sake of Clean

HVACHeaded back around the bend, we are still looking closely at the HVAC systems of today, and more specifically, whether or not we need to concern ourselves with having them cleaned by heating and cooling service in St Louis near Webster Groves MO.  The answer seems to lie, like so many other questions, in the details of your situation. “Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.”  So, it could be more of a question of how much of your heating and cooling system you address in the cleaning process, or just how thorough you ask them to be when you call your St Louis heating and cooling installation near Webster Groves for your next HVAC service.

Many people will agree that the debate is pointless, in fact you may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned. “Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed.”  Also true and found in our recent research on behalf of your St Louis heating service near Webster Groves, is that the EPA does, however, recommend that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning.

If you do decide to have your air ducts cleaned, take the same consumer precautions you normally would in assessing the service provider’s competence and reliability.  You may wish to only pursue those businesses highly recommended to you, such as your St Louis Heating Sales and Service near Webster Groves.

 

HVAC and Mold

HVACWriting today on behalf of your HVAC installation service in St Louis near Jefferson County, we run straight into the in depth subject that begins with a simple question, “Should I have my air ducts cleaned?”  Knowledge about air duct cleaning is actually in its early stages, so a blanket recommendation cannot be offered as to whether you should have your air ducts in your home cleaned, believe it or not. The U.S. Environmental Protection Agency (EPA) urges you to read this document in it’s entirety as it provides important information on the subject and all came from reputable sources online.

According to a recent article found online, “Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts.”  However, there are definitely times when having your St Louis HVAC near Jefferson County cleaned, is highly recommended.  These are specific circumstances that are listed below.

There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems, also, so we have relayed below, on behalf of your St Louis HVAC sales near Jefferson County, what we learned in our research therein.  Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.  It is also recommended that you are aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation.  For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.

Whom to Consider For Commercial Cooling Installation

confusedDid you know that the air temperature in a radiant heated space is lower than in a warm air heated space? What heats the people would be the body comfort maintained as long as these people are in direct line of sight of the heat source.  This is one thing, amongst others, to bear in mind when searching for and deciding upon the best solution for heating and cooling in St Louis near Bridgeton MO.  We set out to explore a couple options for HVAC and cooling is straightforward, whereas heating is a little more in depth in options.

Commercial Warm Air Heating

heating equipmentIn the heating and cooling world of which we are a part, we try to bring to you some of the latest information on behalf of your Heating Installation in St Louis near O Fallon MO.  Some of the most intriguing data comes from subjects that are somewhat fundamental, yet mysterious to most, such as how heating systems actually operate. Today, we will talk about the two main types of heating systems:  warm air and radiant heating in St Louis near O Fallon.

Warm air heating is classified as the first type of heating system and makes use of fan to draw air across a heat exchanger, which increases the temperature of the air and distributes it evenly throughout an area or space. These are ideal for environments requiring constant temperature.  The process involved here is for a warm air heating commercial system in St Louis and starts from a gas or oil fired burner as the initial source of warm air.  Then, hot water circulates throughout the heat exchanger or the electric element.

How are these particular heaters in St Louis installed?  Well, they can be situated by suspending them above the space being heated or mounted on the walls or even on the floor.  For those of you heating a commercial space who need to resort to the floor installation, the following may be important to note, “The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  There is more to discuss here, regarding the warm air heating process and specifics on how these particular heaters work.  Stay tuned for future posts on the subject on behalf of your St Louis Heating Installation near O Fallon MO.

The Door Details of Your Cooling Equipment

detailsLooking at coolers for your restaurant equipment and sales in St Louis, we know that there are several models and styles from which to choose. At your St Louis Cooling Sales near Overland MO, we are into HVAC and commercial restaurant equipment, along with the servicing of any and all of these things.  We want to talk further about the specific details of importance when you are looking for a new walk-in cooler for your commercial restaurant or business.

A very important element of any walk-in, the door must provide access while still preventing cold air from escaping. Plus, the door is the most abused and used part of the walk-in refrigeration system and needs to be able to stand up to frequent use by you and all others who work in your commercial kitchen. Here are a few things that are recommended by experts online that we encountered in our pursuit of valid information on behalf of your St Louis Cooling installation near Overland MO, “Purchasing a unit with a self-closing door mechanism, high quality door hinges and latches, along with well-fitting gaskets can help it last longer and prevent loss of cold air for greater energy efficiency. Other options that you may see include a small window in the door for viewing or door locks to keep your food secure after hours.”

Also, because it may matter to your commercial kitchen layout and your cooling needs, you will want to look at door configuration and location.  “The door location is different from one model to another. Check out the diagram on each product page to see exactly where the door will be located on that particular unit.”  Stay tuned for the next post when we talk about a purchasing check list that may help in your pursuit of cooling equipment for your commercial restaurant needs in St Louis MO.

Radiant Heating in Commercial Environments

radiantWe recently set out to discover the types and ways in which it is best to heat a commercial space in St Louis near Belleville IL.  We found that there are two main styles of heating and that after you understand the area that you are attempting to heat or cool, you will likely be able to better decide which way works best for the space in question.

The first type, which we went into pretty good details over in the previous post here on behalf of your St Louis Heating and Cooling installation and sales near Belleville, is referred to as warm air heating.  Ideal for areas that require a more constant temperature, these commercial heating set ups are usually started with a gas or oil fired burner as the source of heat, then hot water is typically circulated through the heat exchanger or an electric element from there.  There are floor models or those that can be suspended above the space in being heated by your St Louis Heating Service near Belleville.

“The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  Radiant heating is yet the other type of heating in St Louis near Belleville IL and it is a popular way to heat commercial space as well.  Typically provided by radiant tubes that are placed in built-in duct work throughout the roof, the radiant plaque heaters are sometimes used there instead.  In either case though, according to our St Louis Heating sales near Belleville IL, the heat energy is emitted in the form of infrared radiation from the hot surfaces of the heaters. The infrared radiation warms the people or occupants and other objects exposed to it.

Cooling Technology and Movement Activation

motionIn the world of HVAC, we continue to have so much to report and read about.  The latest and greatest innovations continue to sift through the heating and cooling world and make our job reporting the latest news to you pretty fun and rarely ever dull.  One specific and somewhat revolutionary HVAC technologie that could change how we heat and cool our homes as we know it was found in our recent research on behalf of your heating and cooling in St Louis near Jefferson County MO. Many of these HVAC technologies are still on the drawing board, but there are some you can take advantage of now to boost your home’s comfort levels, according to all that we read.

Movement-Activated Air Conditioning was one thing we encountered in our research on behalf of your cooling specialists in St Louis and it has originated from engineers at MIT who have come up with a new air conditioning design that utilizes sensors along aluminum rods hung from the ceiling. Movement then activates these sensors. In other words, the air conditioner only kicks on when people are present.  That may be one of the most efficient cooling set-ups we have seen to date.

“A motion-activated system seems like such a simple, ingenious idea that it’s almost baffling it hasn’t been tried before now. However, this kind of prototype is just one example of how future HVAC systems are going to be more compact and portable, helping to reduce both energy and utility costs.”  Technology is amazing whether it is in the works or already in play in homes and offices and their existing cooling in St Louis near Jefferson County.  Either way, you need to stay on top of the latest in technology in order to find the best cooling system to fit your needs.
